The line below covers up to 5.2 years and opens on the 5Y view; the buttons cut it shorter. Over the last two years (104 weeks) this industry is 11% ahead of S&P 500. Earnings across its companies fell 7% on average over the last four reported quarters.

2 of 38 companies ahead of S&P 500 by 5% or more over three months.

Not ahead of S&P 500 on the three-month view this week; 2 of the 37 companies in the industry index above their 200-day average (11 fewer than four weeks earlier); 2 of those 38 ahead of S&P 500 by 5% or more over three months (3 fewer than four weeks earlier); earnings rising at 13 of the 35 that report earnings.

Participation is shrinking, 5 → 2 of 38 over four weeks, after being ahead of S&P 500. Earnings mixed, 13 of 35 members have higher trailing twelve-month earnings than a year ago.

Both lines start at 200 in the same week, so the gap between them tells the story: the industry line is an equal-weighted index of its 38 companies. The bars underneath are trailing 12-month earnings per share, one bar per reported quarter, each member set to 100 at the start and the industry taking the middle value, so a price line pulling away from flat bars means the market is paying more for the same earnings. A bar turns grey when that figure is lower than the quarter before. The rules are fixed and the same everywhere on this site: ahead by 5% or more over three months, or behind by 20% or more over a year while earnings grew 20% or more. Hover or tap any point to read both values and the gap.

Oil & Gas Equipment & Services has done better than the S&P 500 by 16% over the last 52 weeks. Over 13 weeks the gap is a shortfall of 10.8%. Forum Energy Technologies, Inc. is the strongest against the sector itself at +32.7%.

Oil & Gas Equipment & Services has done better than the S&P 500 by 16% over 52 weeks, but is 10.8% behind over the last 13 weeks. 2 of 30 companies we track are beating the S&P 500 on relative strength (how a share price has done against the index over recent months) (1 has no relative-strength reading yet), and 10 of the 29 with a long enough price history are ahead of the industry itself.

A score that ranks each company against the others in its industry. The four parts shown always add up to the total: Growth & earnings (35), Capital efficiency (25), Valuation (20), and Relative strength (20). Missing or old evidence affects only its own part, never as a hidden adjustment.

Flotek Industries, Inc. has the strongest current balance of earnings trajectory, business quality, valuation and price confirmation, with 71.1% evidence confidence.

Tidewater Inc. scores well on valuation against its peers or its own history, but its earnings have not yet improved enough to back that up.

Ranked last: too little evidence (2 companies)

Under 60% of the evidence behind these scores is available, so they rank after every company above, whatever the score.

Forum Energy Technologies, Inc. has the strongest one-year price move in Oil & Gas Equipment & Services at +157.3%. It also leads on relative strength against the S&P 500, at +20.4%. 2 of 30 companies we track are ahead of the index on that measure (1 has no relative-strength reading yet). Every line covers 314 weekly closes through 4 November 2026.

Price and relative strength

Price · same starting point: Every company, the sector's own index and S&P 500 all start level on the left edge of the window, so only the distance between the lines counts: the highest line has risen the most since then, and the chart at the top of this page is drawn the same way. It opens on one year; the buttons beside it stretch that to three or five.

RS vs S&P 500: How far ahead of or behind S&P 500 each company has been running, measured against its own recent average of that comparison, so the flat line at zero IS S&P 500: above it the company is beating the market, below it the market is beating the company. It opens on one year.

RS vs sector: The same measure taken against Oil & Gas Equipment & Services itself instead of the whole market, so the flat line at zero is the sector: above it the company is beating its own peers, which is the sharper test of the two. It opens on one year.

SLB N.V. has the highest Revenue among the 30 Oil & Gas Equipment & Services companies compared here, at $36,887 million. Baker Hughes Company is next at $27,725 million. WaterBridge Infrastructure LLC has the highest Revenue growth at the 100% top of the scoring scale, so level and change sit with different companies.

What the numbers say: SLB N.V. is the largest at $36,887 million, 33% ahead of Baker Hughes Company. WaterBridge Infrastructure LLC's growth is capped at 100% on the scoring scale; the full change over the last 12 months is 102.4% from a $751 million base, with 8 reported quarters out of the last 20. Fast growth from a smaller base is not yet the same as proven size.

What this means: SLB N.V. is the size to compare against; WaterBridge Infrastructure LLC is the one growing fastest. The faster grower has to keep that growth and turn it into margin and returns before it counts as more than a fast start.

This conclusion weakens if: SLB N.V.'s growth falls below WaterBridge Infrastructure LLC's for two consecutive comparable reports while operating margin also compresses.

Revenue is compared on a common reported-currency basis. Growth is year-on-year, so seasonality does not masquerade as progress.

All-company data · latest reported quarter

In every all-company table on this page, each figure is the company’s latest single reported quarter. The rankings above them use trailing-twelve-month or current-market values, so a company can legitimately show a different number in each.

Revenue shows both size and speed. A large company can absorb shocks and pay for wide distribution; faster growth can mean market-share gains, new capacity or stronger demand. The best sign is usually growth that lasts without hurting margins and returns.

LandBridge Company LLC has the highest OPM among the 30 Oil & Gas Equipment & Services companies compared here, at 66.1%. Archrock, Inc. is next at 35.9%. The same company also has the highest Margin change, at +6.1 percentage points. 29 of 30 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: LandBridge Company LLC leads both opm at 66.1% and margin change at +6.1 percentage points.

What this means: LandBridge Company LLC sets the level to compare against; the company improving fastest needs another report to confirm the change.

This conclusion weakens if: The next two comparable reports reverse the current margin change signal.

Operating margin compares operating profit with revenue. Improvement is measured in percentage points, not percentage growth.

SLB N.V. has the highest Net profit among the 30 Oil & Gas Equipment & Services companies compared here, at $3,097 million. Baker Hughes Company is next at $3,096 million. Flotek Industries, Inc. has the highest Profit growth at the 100% top of the scoring scale, so level and change sit with different companies.

What the numbers say: SLB N.V. earns the most, $3,097 million of profit over the last 12 months, 0% above Baker Hughes Company. Flotek Industries, Inc. shows at least 100% on the scoring scale (171.4% in full) growth from a profit base of $38 million. A fast rate from a small base matters less than a large profit that keeps coming.

What this means: SLB N.V. sets the level to compare against; the company improving fastest needs another report to confirm the change.

This conclusion weakens if: The next two comparable reports reverse the current profit growth signal.

Net profit is the residual after operating costs, interest and tax. Growth off a loss or near-zero base is excluded from the fastest-grower rank.

TechnipFMC plc has the highest ROCE among the 30 Oil & Gas Equipment & Services companies compared here, at 31.8%. Flotek Industries, Inc. is next at 22%. The same company also has the highest ROCE change, at +8.5 percentage points. 30 of 30 companies report a comparable reading, the latest through Jun 2026.

What the numbers say: TechnipFMC plc leads ROCE at 31.8%, 9.8 percentage points above Flotek Industries, Inc. A high return reported once may be one good year; a high return reported year after year shows a lasting business.

What this means: TechnipFMC plc sets the level to compare against; the company improving fastest needs another report to confirm the change.

This conclusion weakens if: The next two comparable reports reverse the current roce change signal.

ROCE asks how much operating return the business earns on the capital employed. Direction matters, but a single exceptional year should not be mistaken for durability.

Liberty Energy Inc. has the lowest PEG among the 30 Oil & Gas Equipment & Services companies compared here, at 0.11×. Innovex International, Inc. is next at 0.13×. Forum Energy Technologies, Inc. has the lowest P/E at −358.7×, so level and change sit with different companies. 19 of 30 companies report a comparable reading, the latest through Sep 2026.

What the numbers say: Liberty Energy Inc. has the lowest comparable PEG at 0.11×, 15.4% below Innovex International, Inc. That would need today's multiple, the company's own history and steady growth to agree.

What this means: A low valuation is a reason to look closer at the business, not a conclusion on its own.

This conclusion weakens if: The next two comparable reports reverse the current p/e signal.

PEG is shown only when earnings are positive and three-year EPS growth is between 5% and 60%. It is worked out the same way every time, as the P/E on the last 12 months of reported earnings divided by that growth rate, never on expected earnings. On Indian companies it is shown only where the two data feeds agreed. Where any of that fails the ratio is left out rather than printed: a P/E divided by a loss, or by growth measured off a tiny base, is a number that looks precise and means nothing.
